b. Consolidation of Scattered Resources : Having multiple officers and multiple office networks means you probably have resources scattered amongst them. These scattered resources signify a few things increased administration. Multiple pieces of hardware and software duplication of effort and so on. This all equates to a higher total cost o f ownership.

A VPPN is an easy way to consolidate thee resource. Which in turn can reduce your total cost of ownership. In addition the hardware and software that remain after consolidation can be applied to increase the availability of those resources.

c.Transparency to Users: One of the major advantages of VPN is transparency of users applications and in most cases even hosts need not that a VPN is in use. Thus adding new software or hardware to your network does not require any more configuration than usual.

d. Reduced Cost : Because a VPN is implemented using a local internet connection the need for dedicated lines and internal dial up infrastructure is removed. The cost of a dedicated circuit whether it s frame relay or ATM link can be a significant initial expense and recurring cost for a company. Maintaining telephone line and RAS equipment can also be cost prohibitive. A VPN can become very attractive when the options are weighed.

e.Ease of Administration :Because the most common VPN configuration the network- network topology is transparent to users applications and hosts relatively nothing is added to the administration or training efforts for these components of your organization.
